/* =====================================================================
   AhuraAuthority.com — v2 "Staircase Hub" homepage.
   New, self-contained brand system (BIS v2.0 "Fortified Growth Engine").
   Deliberately SEPARATE from sales/assets/css/styles.css (the v1 ink/paper
   system). Glassmorphism is allowed here (unlike the v1 zero-shadow rule).

   FALLBACK-FIRST: default styles render a complete, readable, fully-clickable
   static page (no-JS / reduced-motion). journey-init.js adds `.is-enhanced`
   to <body> ONLY when Lenis+GSAP+ScrollTrigger loaded AND motion is allowed;
   the animated 3D overlay lives entirely under `.is-enhanced`.
   Logical properties throughout (RTL-safe, per this project's convention).
